the buoy 11 is automaticallyreleased-when2 the craft to which it is attached sinks to 'ia'i,

predetermined point. p This is caused by the i; or

pressure of the water upon the piston 20,

driving the piston against the'tension of the spring 22 untilthe piston has moved a dis-j. tance suficient to swing the cup-shaped member 12 into the dotted line position shown in 9715* V I V Figure 2. It is obyiousthat' a tensioning of 5 the spring 22 by the-adjusting nut 28' will" f require-a'greater'pressureof water, upon the piston 20before the buoy 11 is released. ,In
